HIV attacks the body by attaching itself to a target cell, then injecting genetic materials which forces the cells to make duplicate of the virus.
There are small population of people that are resistance to HIV/AIDS despite repeated exposure to the virus.
Four reasons why some people cannot get infected with HIV/AIDS.
- High Cytokines: Cytokines are proteins that regulate the duration and intensity of immune response. Studies have shown that people who are resistance to HIV/AIDS have high Cytokines which help in reducing viral entry into host cells and decreases the replication of R5 strain of HIV.
- Strong immune system: Some people’s immune system are strong enough to destroy the virus.
- Mutation: A genetic mutation known as CCR5-delta 32 hampers HIV’s ability to infiltrate immune cells. A few individual carry this mutation in their CCR5 gene.
- High cytotoxic T- lymphocytes: Cytotoxic T-lymphocyte protects the body against HIV when there is consistent exposure to the virus.
